If you had additional hearts distributed throughout your body, what would be one likely advantage and one likely disadvantage?
Lab #4 DNA Profiling Lab 1. Supernatant: denoting the liquid lying above a solid residue after crystallization, precipitation, centrifugation, or other process 2. Soap: destroying all cell membranes, allowing the cell contents to spill out (cell lysis). 3. DNA is only soluble at a pH near physiological levels. The baking soda serves as a buffering system that raises the pH and releases the DNA from bound proteins. 4. The meat tenderizer: is an enzyme (proteinase) that removes proteins bound to the DNA and destroys enzymes (endonucleases) which would chew up the DNA. 5. Since the supernatant is thick from the cellular contents, carefully pouring the alcohol on top of the supernatant leaves two distinct layers.
